Zhejiang Haining Environmental Protection Alliance Standard Fills Up The Tannery Industry Blank
< p > > a href= "http://sjfzxm.com/pioneer/" > Zhejiang < /a > Haining city this year began to implement the technical specification for chrome recovery in tanning chrome tanning wastewater in the tanning industry, the technical standard for the control of odor in tannery sewage treatment plant, and the 3 alliance standards for the technical specification for the recovery of chrome rich sludge for tanning chrome tanning agents, which fills the gap of domestic tannery industry standards. < /p >
< p > it is understood that Haining has a world-renowned Chinese leather city. The tanning industry is an important pillar industry in Haining. The "three wastes" governance has always been a key problem that puzzles Haining's leather industry's sustainable development, and is also a focal point for the leather industry at home and abroad. In order to break through the environmental bottleneck of industry development, Haining quality supervision department actively instruct the Haining Leather Research Institute and Haining leather industry association to standardize the collection of tanning chrome tanning waste water, the precipitation and recovery methods of chromium, the index of waste water after chromium precipitation and the control of comprehensive sludge odor pollution, according to the reality of Haining leather industry, and form 3 alliance standards. < /p >
< < p > < < a href= > http://sjfzxm.com/pioneer/ > to promote the implementation of < /a > standard in Haining.
